Alternatively, theRUI server 100 may include a large format display (LFD), a table top display (TPD) or the like. TheRUI server 100 may provide an UI page of aweb server 120 to the RUIclient 200. TheRUI client 200, which typically includes arectangular display unit 220, may include a portable personal terminal that can be easily carried by a user. TheRUI client 200 may include a monitor or a pivotable television as thesecond display unit 220. - As shown in
FIG. 2 , theRUI server 100 may include afirst communication unit 110, theweb server 120, afirst display unit 130, and afirst controller 140 which controls thefirst communication unit 110, theweb server 120, thefirst display unit 130 and the like. TheRUI client 200 may include asecond communication unit 210, thesecond display unit 220, asensor 230, and asecond controller 240 which controls thesecond communication unit 210, thesecond display unit 220, thesensor 230 and the like. - The
first communication unit 110 and thesecond communication unit 210 may perform the discoveries of theRUI server 100 and theRUI client 200 under the controls of thefirst controller 140 and thesecond controller 240, and receive and transmit various control signals and UI information having an UI page between theRUI server 100 and theRUI client 200. Thefirst communication unit 110 and thesecond communication unit 210 may respectively include communication modules corresponding to various communication methods such as Bluetooth, Wi-Fi (wireless fidelity), zigbee, IR communication, RF communication, and wired communication. - In the meantime, middleware such as UPnP, HAVi, java intelligent network infra-structure (JINI), video electronics standards association (VESA), and digital living network alliance (DLNA) may support a home networking capable of sharing digital contents such as music, picture, and video stored in an electronic apparatus such as a computer, a home electric product, and a portable terminal. The
first communication unit 110 and thesecond communication unit 210 in accordance with the present exemplary embodiment may perform communication of the RUI based on the Internet and the UPnP network according to a web-based protocol standard and a CEA-2004 standard defining a frame work. Here, CEA-2004 is the acronym for web-based consumer electronics association's-2004. - The
web server 120 may provide a web-based UI page to the RUIclient 200. - Each of the
first display unit 130 and thesecond display unit 220 may include a plasma display panel, an organic light-emitting panel made of an organic material, a liquid panel having a liquid layer or the like to display an image signal and further include a panel actuator which actuates such a panel. As shown inFIG. 1 , when theRUI server 100 is a television, theRUI server 100 may include thefirst display unit 130. However, thefirst display unit 130 may not belong to essential components and thus be omitted. Thesecond display unit 220 may display an UI page received from theRUI server 100. - The
sensor 230 in theRUI client 200 may sense a user selection of selecting one of a horizontal mode for displaying the RUI horizontally and a vertical mode for displaying the RUI vertically. Thesensor 230 may also include a gyrosensor which senses a direction in which thesecond display unit 220 is moved vertically or horizontally by a user or a user input unit such as a touch panel which senses a user's input. The configuration of thesensor 230 is not limited to a specific hardware. Information sensed through thesensor 230 may be transferred to thesecond controller 240. - The
second controller 240 may discover theRUI server 100 according to the RUI standard such as CEA-2014 through thesecond communication unit 210 and then start the communication with theRUI server 100. The detailed description related to such discovery will be omitted. In theRUI client 200 of the present exemplary embodiment, thesecond controller 240 may include a control point. Of course, in the case that the control point is separated from theRUI client 200, the discovery may be performed by such an external control point and UI information may also be transmitted to theRUI client 200 through the control point. - If the communication with the
RUI client 200 is started, thefirst controller 140 may transmit UI information having horizontal and vertical UI information to theRUI client 200. -
FIG. 3 is a control flowchart showing a method of controlling the UI providing system shown inFIG. 2 . Hereinafter, an UI providing method will be described with reference toFIG. 3 . - As described above, the
RUI server 100 and theRUI client 200 may first discover each other to start the communication with each other (S10). - After such a discovery operation, a profile matching is performed between the
RUI server 100 and the RUI client 200 (S20). Information related to thesecond display unit 220, e.g., usable resolution, the number of pixels, UI profile and the like may be transferred to theRUI server 100. Then, an UI based on such profile matching may be transmitted to theRUI server 100. - If the
RUI client 200 requests an UI page (S30), theRUI server 100 may transmit to theRUI client 200 UI information having horizontal and vertical UI information corresponding to the requested UI page (S40). TheRUI server 100 of the present exemplary embodiment may transmit to theRUI client 200 UI page I having both a horizontal and a vertical UI page II and III as shown inFIG. 4 . In other words, theRUI server 100 may transmit to theRUI client 200 one HTML script including information related to the horizontal and the vertical UI page. In one HTML script, a function for changing any one of the horizontal and the vertical UI page to the other UI page may be included in a script, e.g., java script. - The
second controller 240 may generate and display an UI page according to a user selection (S50). For example, when the UI page is requested, if a display mode of thesecond display unit 220 is a horizontal mode, thesecond controller 240 may select and display the horizontal UI page II of the transmitted UI page I. Thesecond controller 240 may include a HTML web browser for rendering and displaying the transmitted UI. - Thereafter, if the display mode is changed by a user (S60), i.e., the display mode is changed to a vertical mode, the
second controller 240 may generate the vertical UI page III corresponding to the changed vertical mode to display it on the second display unit 220 (S70). Thesecond controller 240 may call a function in form of a script corresponding to the horizontal or the vertical mode. Then, the displayed UI page may be changed by the called function. In accordance with the present exemplary embodiment, when the profile matching is performed, if one UI page I is received, a UI page corresponding to the display mode selected by a user may be displayed without an additional interaction with theRUI server 100 even though the display mode is changed by the user. In addition, since theRUI client 200 merely re-generates the UI page by using the given information without adjusting or changing the resolution of the UI page, it is possible to display the high-quality UI page having high reliability. - According to a related art method, when the profile matching between an RUI server and an RUI client is performed, a UI profile is not able to be changed after an optimized UI profile information is selected considering a second display unit. Accordingly, even though a user changes a display mode, a UI page according to the fixed UI profile is provided to the RUI client. Therefore, an inadequate display mode may be displayed. Specifically, an upper or a lower end of the UI page may be cut in a horizontal mode and a left or a right end of the UI page may be cut in a vertical mode. Alternatively, the UI page may be extended in a vertical or a horizontal direction. As a result, it is difficult for the user to display a clean high-quality UI page.
- The
RUI server 100 of the present exemplary embodiment may provide theRUI client 200 with both the horizontal UI page corresponding to the horizontal mode and the vertical UI page corresponding to the vertical mode. TheRUI client 200 may selectively generate and display any one of the horizontal and the vertical UI page as the UI page according to a user's request. In other words, theRUI client 200 may display an UI page desired by a user without additionally adjusting a resolution by using received UI information. - If the display mode is changed, the
second controller 240 may apply a selected area to the changed mode (S80).FIG. 5 shows how the selected area is applied. As shown inFIG. 5 , if the display mode is changed from the horizontal mode to the vertical mode, an area A that was selected or actuated in the horizontal mode may become an area B that is maintained to be selected or actuated even though the UI page is changed. In other words, an icon “+” that has been actuated in the horizontal mode, i.e., in the horizontal UI page may also be being actuated in the vertical mode, i.e., in the UI page. Thesecond controller 240 may apply a selected area to the changed display mode such that a user is able to keep performing a work or a control that has been performed even if the display mode is changed. -
FIG. 6 is a control flowchart showing a method of controlling the UI providing system shown inFIG. 2 , according to another exemplary embodiment. In even the present exemplary embodiment, the stage S10 where the discovery between theRUI server 100 and theRUI client 200 is performed to start the communication and the stage S20 where the profile matching therebetween is performed are also carried out as shown inFIG. 3 . - If the profile matching is performed or the
RUI client 200 requests an UI page, thefirst controller 140 may transmit to theRUI client 200 horizontal UI address information and vertical UI address information, i.e., both URLs related to a horizontal UI page and a vertical UI page (S100). In other words, thefirst controller 140 may transmit to theRUI client 200 all address information related to the two UI pages instead of transmitting thereto only one of the horizontal and the vertical UI address information according to the related art method. - If the horizontal mode is selected by a user (S110), the
second controller 240 may request an UI page based on the horizontal UI address information (S120). - According to the request of the
RUI client 200, theRUI server 100 may transmit to theRUI client 200 UI information having the horizontal UI page information (S130). Then, thesecond controller 240 may display a horizontal UI page based on the transmitted UI information. - Thereafter, if the display mode is changed (S60), the
RUI client 200 may request an UI page based on the vertical UI address information (S140). Then, theRUI server 100 may transmit to theRUI client 200 UI information having the vertical UI page information (S150). - In accordance with the present exemplary embodiment, if an event for changing the display mode is generated by a user, the
second controller 240 may call a function in a script. Then, the called function may request an UI page in an URL adequate for the changed mode. At this time, theRUI server 100 may not perform additional operation or control except for providing the UI page of the requested URL. - In addition, in the present exemplary embodiment, if the display mode is changed, the
second controller 240 may apply a selected area to the changed mode. When transmitting to the UI information having the vertical UI page information, theRUI server 100 may additionally transmit information related to the selected area. Thesecond controller 240 may also change the selected area based on the information. -
FIG. 7 is a control flowchart showing still another method of controlling the UI providing system shown inFIG. 2 . - When the profile matching is performed or the
RUI client 200 requests an UI page, thefirst controller 140 may insert any one of the vertical UI address information and horizontal UI address information into the other UI address information and transmit it to theRUI client 200. - For example, when the display mode of the
second display unit 220 is the horizontal mode, if a user requests an UI page (S30), theRUI server 100 may transmit a horizontal UI page and insert vertical UI address information into UI information related to the horizontal UI page before transmitting it thereto. In other words, theRUI server 100 may insert a vertical UI URL into a HTML script related the horizontal UI page and transmit it to theRUI client 200. - Then, if the display mode is changed (S60), the
RUI client 200 may request an UI page based on the received vertical UI address information (S170). Then, theRUI server 200 may transmit a vertical UI page (S180). - If the
RUI client 200 requests an UI page when the display mode of thesecond display unit 220 is the vertical mode, theRUI server 100 may transmit a vertical UI page and insert horizontal UI address information into UI information related to the vertical UI page before transmitting it thereto. - In the exemplary embodiment, when RUI transmission is performed, if a user changes the display mode, the
RUI server 100 may transmit all information to theRUI client 200 to provide an UI with a high reliability without additional control or manipulation of theRUI client 200 and theRUI server 100. - As described above, there is provided an RUI server and an RUI client and a method of controlling the same, capable of easily changing a horizontal and a vertical UI.
- In addition, there is provided an RUI server and an RUI client and a method of controlling the same, which provide an accurate and clean UI without change of the UI by the RUI client.
- Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
